Dust Reduction Device for Building Engineering

TECHNICAL FIELD

The present invention relates to the technological field of civil engineering, particularly to a dust reduction device for building engineering.

BACKGROUND

Currently, a large amount of dust is inevitable at construction sites of building engineering due to the required handling of multiple equipment and noisy environment. On the one hand, the dust pollution will reduce the field of vision and affect on-site operations such as tower crane transportation. On the other hand, the long-time exposure to the dusty air will cause great harm to the workers' health. In the prior art, dust reduction is carried out by installing a dust reduction device or arranging a spray device above an enclosure barrier. For example, the patent with Publication No. CN218281088U discloses a dust reduction device for building engineering, the device includes a water tank, a water pump fixed upon the water tank, a pumping pipe rigidly connected at the bottom of the water pump, a connecting pipe fixedly connected at the top of the water tank, a spraying head fixedly connected at the top of the connecting pipe, a mounting mechanism fixedly connected at the rear side of the water tank, and a positioning mechanism arranged in the mounting mechanism. The mounting mechanism includes a connecting block, which is fixedly connected to the rear side of the water tank. Through the arranged mounting mechanism, the workers only need to rotate a torsion plate to mount the water tank upon the enclosure barrier, there is no need for the workers to use a drilling machine to drill and fix it in the enclosure barrier, which reduces the damage to the enclosure barrier, and the operation is simple and convenient for the workers to use, and promoting the work efficiency for the workers when disassembling and replacing the position of the dust reduction device. However, the following problems still exist:

(1) Fixed mounting on enclosure barriers requires a large number of spray devices during road construction or strip construction sites. Since most constructions are locally conducted, the use of fixed spraying dust reduction devices will occupy a large space on the ground and affect normal traffic.
